Camp Knock Knock

Willie and Crow are back at camp. Last year, Willie won the joke contest and was the knock-knock king. Now Crow wants to get him back. But Willie has a secret weapon-or does he? This time Crow takes charge as Willie must solve the clues hidden in knock-knock jokes to get back his secret weapon-a knock-knock joke book. If Willie would change into clean clothes while at summer camp, he may find the joke book which Crow has hidden from him.
